IMPROVEMENT IN GUIDES FOR SETTING LUMBER.

Specification forming part of Letters Patent No. 152,963, dated July 14,1874; application filed May 16, 1874.

To all whom it may concern:

Be it known that 1, PETER BERRY, of Millcrstown, in the county ofOhampaign and State of Ohio, have invented a new and 1111- proved Guidefor Setting Lumber, of which the following is a specification:

In the accompanying drawings, Figure 1 represents a top view of myimproved guide for setting lumber; Fig. 2, an end view of the same.

Similar letters of reference indicate correspondin g parts.

The invention consists in an improved de-.

vice for gaging the thickness of boards or other forms of lumber as cutfrom logs in the ordinary operation of sawing.

The frame A of the gage is designed to be bolted to the mill-frame, andthus be stationary near the saw and opposite the ways on which thelog-carriage travels. The aligned screw-shaft G and graduated shaft 0are supported in vertical standards A swiveled together at E, as shown.An index or pointer, F, is arranged opposite the graduatedportion ofshaft 0 to indicate the degree of longitudinal adjustment of the same,which is efl'ected by turning the screw-shaft by means of the hand-wheel0 A guide or head, D, is attached to the outer end of the shaft 0, so asto hang vertical by its own gravity. The screw 1) performs the oflioe ofa clamp for the screw-shaft to hold it in any adjustment.

The manner of using the device is as fol lows: A slab is first out offfrom the log in the usual way, the head D turning up into a horizontalposition as the log advances. The head is then adjusted toward the logbeyond the plane of the saw to the extent of the thickness of board orother form of lumber to be cut from the log. Thereafter, each time a cutis made, the log is adjusted on the head-blocks till its straight sidecomes in contact with the head D, which thus acts as a stop or gage.When the log is being fed to the saw it moves in frictional contact withthe head. The thickness of out can be quickly and accurately varied byadjusting the shaft 0 in the bearings.

What I claim is In a device for gaging lumber, the combination ofscrew-shaft U and graduated shaft 0 swiveled together, as shown, theindex F, and head D, said parts being arranged on the frame A A, asdescribed, to operate as specified.
